You mean the character pieces? Yeah, they are pretty tasty, aren't they? That's the box art from the G1 toys. The other pics appear to be screencap equivalents from the cartoon (prints of cels, something like that?).

I was not even aware of these until I bought an almost complete set (minus the color variants) from a local toy show dealer in minty shape all in card pages and protected in a binder for about $5 or so. A steal! Now, if I could only finish the set....anybody wanna trade/sell some? PM me with what ya got!

We certainly need more Transformers cards. I've got an old G1 TF card game where you had to collect full transformations for each character (a card each for robot, mid-transformation, and alt mode) and the one with the most transformations wins. Still got the price sticker on the box too.
I quite enjoyed the cards that came with the Beast Wars board game as well.
Heck, just give us more art cards. No need for games really. Although a decent TF CCG would be nice.
